It used to be called "the Castle", when West Ham moved there in the 1904/05 season, although fans called it "the Cabbage Patch".

According to the club's website, "The field in which the pitch was to be laid was originally used to grow potatoes and cabbages and, as such, the pitch was often referred to by the locals as 'The Potato Field' or 'The Cabbage Patch', while the ground itself was originally named ‘The Castle’."

The reason it was called that is because it was built in the grounds of an old stately home, called Green Street House but widely known as "Boleyn Castle".
